Claims

[Scope of utility model registration request]

A resin base in which a rotating shaft having an uneven part for fixing the shaft is press-fitted into a center hole, and a flat part is exposed on the outer peripheral surface of this base,
This flat part has a small number of commutator pieces (each having a large number of commutator pieces configured such that a claw part provided at one end bites into the base part,
In a motor commutator in which this commutator piece and an armature coil are electrically connected, the rotating shaft uneven portion and the resin base are engaged in an area other than the brush sliding support portion of the base. Naru motor communication □Evening.
